Function faux::matcher::any

pub fn any<T: ?Sized>() -> impl ArgMatcher<T>

Returns a universal argument matcher.

The returned matcher will match any T

Examples

struct Data;

use faux::matcher::{self, ArgMatcher};

assert!(matcher::any().matches(&5));
assert!(matcher::any().matches("hello"));
assert!(matcher::any().matches(&Data));

Usage within when!

For convenience, faux::when! uses _ to denote the any matcher. See the matcher syntax for more information.

// `_` means the `any` matcher
faux::when!(my_struct.some_method(_)).then_return(5);

// we can also call it manually within `when!`
faux::when!(my_struct.some_method(_ = faux::matcher::any()))
    .then_return(5);

// or call it manually outside `when!`
faux::when!(my_struct.some_method)
    .with_args((matcher::any(),)).then_return(5);
